Description
Technical field
The present invention relates to a kind of round roller screen and drive unit, belong to round roller screen technical field of structures.
Background technology
Existing round roller screen mainly is divided into two kinds; A kind of as shown in Figure 1; Comprise the sieve bucket 1-3 that is installed on the support 1-4, the shaft coupling 1-2 that the end of support 1-4 is equipped with reducing motor 1-1 and is connected with reducing motor 1-1, the other end of support 1-4 is equipped with supporting bearing base 1-5; Wherein the internal structure of sieve bucket 1-3 is as shown in Figure 3; Comprise the axle 3-2 that is installed in the sieve bucket 1-3, axle 3-2 one end is connected with shaft coupling 1-2, and the other end is connected with supporting bearing base 1-5; Be interval with disc 3-5 on the axle 3-2; The screen cloth that sieve bucket 1-3 goes up set different apertures will sieve a bucket 1-3 and be separated into a plurality of hoppers, be followed successively by No. three material passage 3-4, No. two material passage 3-3, expects passage 3-1 No. one that from charging aperture hopper upper screen cloth sieve aperture increases gradually; 1), its running part is inner for axle directly runs through sieve bucket 1-3 mainly there is following shortcoming in above-mentioned round roller screen:, two ends are supported by bearing, directly are connected through shaft coupling 1-2 and reducing motor 1-1 to drive; Be characterized in that sieve bucket 1-3 has the disc supporting at the charging aperture place, material impacts disc, serious wear always during charging; Be difficult for changing, maintenance cost is high, and axle directly runs through sieve nest in addition; The suffered moment of torsion of axle is bigger, needs the bigger diameter of axle; 2), can only the screening material be sieved by aggregate size order from small to large successively; Aniseed just can sift out at last, and the time that has caused aniseed in roller screen, to stop is long, and maximum aggregate is all through three kinds of screen clothes; Quickened the wearing and tearing of screen cloth, needed driving power strengthens; 3), the screen cloth distribution form adopted single-deck screen mesh screen branch, under the situation that guarantees sieving area, needs the length of lengthening roller screen, increased cost of manufacture;
Another kind of as shown in Figure 5, its sieve bucket is the same with above-mentioned sieve bucket, but drive unit is different, and its drive unit comprises support 5-1, reducing motor 5-2, bearing block 5-4, idler pulley 5-5, rolling ring 5-6; Sieve bucket 5-3 holds the rolling ring 5-6 on the sieve nest through four idler pulley 5-5, and reducing motor 5-2 drives idler pulley 5-5 and drives through accomplishing with rolling ring 5-6 function of friction, and this kind equipment cost is than higher; The concentricity requirement of roller screen is higher, complex manufacturing technology, and sieve bucket 5-3 directly is placed on the idler pulley through the rolling ring 5-6 on the sieve nest; Have only through gear wheel to prevent play, there is the play phenomenon in whole sieve nest, when debugging in the building site; Four-wheel friction drives and is difficult for adjustment, if four idler pulley position adjustments are improper, is prone to cause rolling element to swing; The roller screen phenomenon that drops can take place when serious, has certain potential safety hazard.
